The combination of climate change impacts, declining fluvial sediment supply, and heavy human utilization of the coastal zone, arguably the most populated and developed land zone in the world, will very likely lead to massive socioeconomic and environmental losses in the coming decades. Effective coastal planning/management strategies that can help circumvent such losses require reliable local scale (<~10 km) projections of coastal change resulting from the integrated effect of climate change driven variations in mean sea level, storm surge, waves, and riverflows. Presently available numerical models are unable to adequately fulfill this need. A new generation of multi-scale, probabilistic coastal change models is urgently needed to comprehensively assess and optimise coastal risk at local scale, enabling risk informed, climate proof adaptation measures that strike a good balance between risk and reward. With approximately 10% of the global population living in the coastal zone 1 , the potentially massive impact of climate change on the world's coastal zones is now well recognized 2-6. Moreover, continued human attraction to the coast has resulted in rapid expansions in settlements, urbanization, infrastructure, economic activities and tourism, as exemplified by 15 of the world's 20 megacities being located in the coastal zone 7. The combination of climate change impacts, declining fluvial sediment supply 8,9 , and the ever increasing human utilization of the coastal zone is very likely to result in unprecedented socioeconomic and environmental losses in the coming decades 10-15. For example, the economic losses due to flooding alone in coastal cities is expected to be around US $ 1 Trillion by 2050 16. Similarly, the cost of forced migration due to just sea level rise (SLR) driven coastal erosion over the 21 st century is also expected to be around US $ 1 Trillion 2. Effective coastal planning/management strategies that can help circumvent such losses through adaptation require reliable projections of coastal change. This perspective addresses the question of how we may obtain such projections using numerical modelling techniques.
